Four linked novels from four authors. After the extinction asteroid does not strike Earth, the dinosaurs keep evolving--but so do the mammals. We mammals have achieved humanlike shapes, but now it's cold-blooded, magic-using reptiles against hot-blooded, hot-tempered descendants of cats. In a heroic Bronze Age world similar to 300, the Mrem Clans expand their territory but now face the Lishkash, reptilian masters of a cold-blooded empire of slave armies and magic. It's mammalian courage and adaptation against reptile cunning in a clash of steel, magic and will to determine who shall inherit the Earth
